Study of the dynamic resistance of amorphous alloys during the structural relaxation processes

The effects of the annealing treatment on the temperature coefficient of electrical resistivity of amorphous Fe80.5W5B14.5and Fe41Ni39P12B8alloys have been investigated by means of the d.c. four-probe method. The experimental results indicate that the temperature coefficients of electrical resistivity of the specimens increase after the annealing treatment. We have analysed the characteristics of electronic transport of the amorphous alloys in the structural relaxation process and have observed that annealing treatment increases the temperature coefficient of resistivity of the amorphous alloys.
